DEVICE AND METHOD TO ACCURATELY AND EASILY ASSEMBLE
GLASS SLIDES
TECHNICAL FIELD
[0001] Embodiments of the present invention relate generally to
laboratory devices and
more specifically to systems and methods for the preparation and assembly of
slide arrays for
further experimentation.
SUMMARY OF THE EMBODIMENTS
[0002] According to some embodiments of the present invention, a device
accepts a slide
array that is to be assembled. A book-like hinged device can be constructed
such that two
surfaces with location points are exposed to facilitate the loading of two
separate slides. One
leaf of the book-like device is constructed such that it is a fixed mounting
surface placed upon a
bench top or other such piece of furniture. The other leaf of the book-like
device is moveable
from a fully open configuration to a full closed configuration, approximately
180 degrees of
motion. Upon closing the hinge, the action brings two slides together in an
accurate, repeatable,
and easily managed manner. In the preferred configuration, a vacuum chuck on
the moveable
leaf of the book-like device holds a moveable slide firmly in place prior to
its placement on top
of a fixed slide. A spring loaded catch on the upper, moveable portion of the
device can also
maintain a hold on a slide during operation. The vacuum is applied on command
of the operator.
The closing of the book-like device brings the moving slide and the fixed
slide into close but not
intimate contact. Once the operator releases the vacuum upon command, the two
slides are
brought into final, resting position with a minimum of impact.
[0003] According to some embodiments of the present invention, the slide
array is to be
assembled inside of a separate carrier to allow further processing. The fixed
slide is to be
assembled inside of the carrier and then placed on a tooled spot on the fixed
leaf of the book-like
device. Further processing can include the application of an additional
carrier on the top slide
and the addition of a screw-type clamp to fixate the slide array.
[0004] According to some embodiments of the present invention, the slides
described
herein are composed of a transparent glass. The invention is not limited to
the size of glass slide

normally encountered in normal laboratory operations. The slides can be of a
large variety of
sizes and shapes. The slides need not be of identical sizes, smaller slides
can be placed on a
larger slide or vice versa. The slides need not be composed of transparent
glass, other materials
such as metals or plastics can be accurately assembled using the herein
described device.
[0005] Various modifications and additions can be made to the exemplary
embodiments
discussed without departing from the scope of the present invention. For
example, while the
embodiments described above refer to particular features, the scope of this
invention also
included embodiments having different combination of features and embodiments
that do not
include all of the above described features.

DETAILED DESCRIPTION
[0017] Unless otherwise indicated, all numbers expressing quantities of
ingredients,
dimensions reaction conditions and so forth used in the specification and
claims are to be
understood as being modified in all instances by the term "about."
[0018] In this application and the claims, the use of the singular
includes the plural unless
specifically stated otherwise. In addition, use of "or" means "and/or" unless
stated otherwise.
Moreover, the use of the term "including," as well as other forms, such as
"includes" and
"included," is not limiting. Also, terms such as "element" or "component"
encompass both
elements and components comprising one unit and elements and components that
comprise more
than one unit unless specifically stated otherwise.
[0019] With reference to Fig. 1, the Accurate Slide Assembly Device
(ASAD) 100
consists of a base 101 whereby the static slide assembly tooling base 102 is
solidly affixed in
place, according to the embodiments of the present invention. Attached to the
tooling base 102
is the moveable arm 103 via hinge 105 that keeps the respective tooling
points, lower hybaid
tooling area 108 and upper slide chuck 110, in accurate registration or
alignment with one
another, according to the embodiments of the present invention.
[0020] With reference to Figs. 1, 2, and 4, Groove 107 (as shown in Fig.
1) allows the
placement of a flexible seal 111 (as shown in Fig. 2), such as an o-ring, into
the upper slide
3

CA 02843507 2014-01-28
WO 2013/026013 PCT/US2012/051400
chuck 110 to provide a vacuum to be held in the vacuum space 106 once an
experimental slide
113 (as shown in Fig. 4) has been placed in the upper slide chuck 110,
according to the
embodiments of the present invention. With reference to Fig. 4, hard tooling
points 115 fix the
experimental slide 113 in a tightly constrained location, according to the
embodiments of the
present invention.
[0021] With reference to Fig. 3, lower slide receiver 112 is the part of
the Hybridization
chamber base fixture that receives the hybridization gasket slide 114.
Hybridization gasket slide
114 preferably includes several of chambers thereon in which material for
processing may be
added. Each chamber may be surrounded by a gasket or a flexible seal (similar
to the flexible
seal 111 above). Once the hybridization gasket slide 114 has been prepared by
adding material to
the surface, the operation of the ASAD 100 can commence, according to the
embodiments of the
present invention.
[0022] With reference again to Fig. 4, the experimental slide 113 is held
in place against
the o-ring 111 (as shown in Fig. 2) after a vacuum is imposed in the open
volume or vacuum
space 106 (as shown in Figs. 1 & 2). In the present configuration, as
illustrated in Figs. 4 ¨ 6, the
vacuum is generated by manually pushing button 109 down on the spring return
cylinder 104 and
then releasing the button 109 to allow the spring to drive the piston inside
of the cylinder 104
upwards. A flexible tube 117 connects the cylinder generated vacuum to the
open volume or
vacuum space 106 (as shown in Figs. 1 & 2) in the moveable arm 103, according
to the
embodiments of the present invention.
[0023] With reference to Figs. 7 ¨ 9, once the experimental slide 113 is
firmly seated
against the o-ring 111 (as shown in Fig. 2) and sufficiently registered in the
hard tooling points
115, the moveable arm 103 can be articulated by rotation and the experimental
slide 113 can be
placed over the hybridization gasket slide 114 and inside of the lower slide
receiver 112,
according to the embodiments of the present invention. The moveable slide
(e.g., experimental
slide 113 in this embodiment) is located in a controlled position so that as
the slides (e.g.,
experimental slide 113 and hybridization gasket slide 114 in this embodiment)
are brought into
close proximity with each other, there will be no interference with the
removable tooling (e.g.,
lower slide receiver 112 in this embodiment) or the stationary slide (e.g.,
hybridization gasket
slide 114 in this embodiment). This location is provided in the present,
preferred configuration

WO 2013/026013 PCT/US2012/051400
by raised surfaces that are carefully designed to press against the periphery
of the moveable
slide, without interfering with the rest of the tooling or the fixed slide.
[0024] With reference to Figs. 10 & 11, the experimental slide 113 can
then be released
by depressing the button 109 (as shown in Figs. 1 ¨ 9) and allowing the
cylinder spring to drive
the cylinder 104 to its neutral state. This action causes the vacuum to be
released to atmospheric
pressure and the experimental slide 113 falls onto the hybridization gasket
slide 114 under the
force of gravity, according to the embodiments of the present invention.
[0025] With reference again to Fig. 10, the small distance 118 between
the experimental
slide 113 and the hybridization gasket slide 114 allows the eventual placement
of the
experimental slide 113 and the hybridization gasket slide 114 (as illustrated
in Fig. 11) to be
gentle and non-disruptive event, according to the embodiments of the present
invention. In this
embodiment, the distance 118 is preferably, but not limited to, a distance on
the order of about 1
millimeter or less.
[0026] With reference once more to Fig. 1, the grooves 116 that are
placed in static slide
assembly tooling base 102 are present to allow a clamp (not shown) to be
applied onto a stack of
hybridization base, hybridization gasket slide, printed slide and the
hybridization chamber top in
order to fixate the two slides (as shown in Fig. 11) one on top of the other
and held in place by
the hybridization top in order to facilitate further processing, according to
the embodiments of
the present invention. Once gravity has brought the upper slide (i.e.,
experimental slide 113) into
contact with the lower slide (i.e., hybridization gasket slide 114), it is
possible to clamp the slides
together without disturbing the orientation thereof. The device may now be
used to repeatably
fixate other pairs of slides.
[0027] The Accurate Slide Assembly Device (ASAD) 100 is intended to take
a first
prepared or otherwise unused slide (including, but not limited to,
experimental slide 113) and
place it in close proximity in a parallel attitude to a second prepared or
otherwise unused slide
(including, but not limited to, hybridization gasket slide 114). Prior to
positioning in either upper
slide chuck 110 or the lower slide receiver 112, either of the first and
second slides may be used
or unused, prepared or unprepared, already processed or not yet processed.
[0028] In the above-described embodiment, vacuum was provided using the
assembly ¨
comprising the manually actuated button 109 and spring return cylinder 104 ¨
that is connected
to the o-ring-lined upper slide chuck 110 via flexible tube 117. This,
however, is not the only

CA 02843507 2015-12-10
method of supplying a vacuum to the ASAD 100. Other sources of vacuum include,
but are not
limited to, an external source that can be piped to the instrument, an on-
board source that can be
generated with a bulb commonly found in laboratories used for operating
pipettes, and an air
cylinder that is manually operated to provide a sufficient vacuum to pull the
slide against an o-
ring. The required vacuum pressure is on the order of inches of water (or
about 2.5 to 25 mbar).
[0029] For the above-described embodiment, releasing the vacuutn to
atmospheric
pressure may be accomplished via use of one of numerous valving options that
are known to
those skilled in the art.
[0030] In the above-described embodiment, the device is manually operated,
but the
device may be configured to operate robotically in ways known to those skilled
in the art. In the
above-described embodiment, a single hinge 105 is used, because it is the
easiest configuration,
but a combination of hinges and slides may also be built into the device to
accomplish the same
or similar task. Either slides, hinges, or both fit the task.
[0031] Although the above-described embodiment utilizes a hybridization
chamber base,
the device need not have a hybridization chamber base, but may simply be used
to assemble the
slides.
[0032] In some embodimcnts, the upper slide chuck 110 may be configured to
be
adjustably shifted alone any direction within a plane that is parallel to the
surface of the
moveable arm 103, in order to allow for ease of alignment between the
experimental slide 113
and hybridization gasket slide 114 when the moveable is rotated to a position
above the static
tooling base.
[0033] Various embodiments of the disclosure could also include
permutations of the
various elements recited in the claims as if each dependent claim was a
multiple dependent claim
incorporating the limitations of each of the preceding dependent claims as
well as the
independent claims. Such permutations are expressly within the scope of this
disclosure.
